TRANSMISSION MECHANISM.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Original application filed May 25, 1903, Serial No. 158,714. Divided andthis application filed May 4, 1906. Serial No. 315,230.

To all whom it may concern:

Be it known that I, ALEXANDER TINTON, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Transmission Mechanism,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to improvements in transmission mechanism, whichis especially adapted for use in automobiles, and is a division of myapplication filed May 25th, 1903, bearing Serial Number 158,7 1 1.

In the accompanying drawings, Figure l, is a top plan view, partly insection, of a transmission mechanism which embodies my presentinvention. Fig. 2, is an enlarged side elevation of the reversingmechanism. Fig. 3, is a plan view of a motor vehicle frame with myinvention in place thereon.

The present invention pertains to a mechanism for transmitting powerfrom the engine shaft for propelling the vehicle, and which includesmeans for disconnecting the engine from the transmitting mechanism, andthe mechanism for reversing the motion of the driven mechanism andthereby backing the vehicle.

The rear end of the engine shaft 12, as here shown, carries a device fortransmitting the motion. This device acts as a fly-wheel for the engine,and consists of a disk 89 to which is attached a laterally-extendingcollar 88, the inner surface of which acts as a clutching face. A member90 is located within the collar or balance wheel 88, and carriesfriction shoes 91 adapted to engage and disengage the interior surfaceof the collar in any desired manner. This clutch is carried upon one endof a short shaft 92, the opposite end being journaled in a bearing 93which is supported from a cross bar 9 1. The clutch is controlledthrough the medium of a lever 95 having one end provided with a yoke 96engaging a movable collar 97. A shaft 102 has one end connected with theouter end of the short shaft 92 through the medium of a suitableuniversal joint or connection 103. The opposite end of this shaft 102 issuitably operatively connected with the driving wheels 100 of thevehicle, through the usual compensating gear located in an inclosure101. When the clutch is in engagement with the collar 88, the engineshaft 12 is directly connected with the driven shaft 102, and the engineis driving direct for the forward propulsion of the vehicle.

The reversing mechanism consists of a gear 109 carried by the member 90,and a rocking frame 110 is pivotally connected to the adjacent side sillof the vehicle frame, or other suitable support, at a point 111 throughthe medium of a bracket 112. Journaled in this rocking shaft 110 is agear 114, and this gear is adapted to mesh with the gear 109. A shaft115 is journaled in the rocking frame 110, and this shaft carries apinion 116 which is constantly in mesh with the gear 114. Carried by theshaft 115 is a friction roller 117. The operation of this reversingmechanism is as follows z- Nhen the rocking frame 110 is caused toassume the position shown in Fig. 2, through the medium of an operatingrod or connection 118, the gear 114 is brought slightly into mesh firstwith the gear 109, which is carried by the member 90. A further movementof the rocking frame will cause the friction disk 117 to engage theouter surface of the balance wheel or collar 88. At this time the clutchis out of contact with the balance wheel, and the friction roller 117 isin engagement with the balance wheel, and causes the clutch member 90through the intervention of the pinion 116, and gears 114C and 109, torevolve in a direction opposite the direction of revolution of thebalance wheel, and thus impart to the shaft 102 a reverse revolution forbacking the vehicle. l/Vhen this reversing mechanism is not in operation, the rocking frame 110 is carried to a position which disengagesthe gears 114: and 109, and as a consequence carries the friction roller117 out of contact with the balance wheel 88, and the reversingmechanism is entirely out of operation when the clutch member 90 isthrown into action with the balance wheel for driving the vehicleforward. From this it will be observed that when the vehicle is beingdriven forward, the clutch member and balance wheel 88 make a directdrive from the engine shaft 12 to the driven shaft 102. There being nointervening gearing in operation, and no idly rotating reversingmechanism, the forward transmission mechanism here shown is very quietrunning, and saves the wear co-acting directly with the balance wheeland tear upon idly revolving mechanism, and said driven shaft to rotateit in one diand also the power necessary to drive it.

The shafts of the driving wheels 100 of the vehicle are connected by acompensating gearing of any suitable form which are so well understoodby those skilled in the art that any specific illustration ordescription thereof is unnecessary. This compensating gearing is locatedin a suitable boxing 101, and the shaft 102 has its rear end operativelyconnected with the compensating gearing in a well known way, and theforward end of the shaft 1.02 is connected with the short shaft 92 bymeans of a suitable form of universal joint 108, and preferably there isa universal joint 104 at the opposite end of the shaft 102. Thisuniversal arrangement is for the purpose of permitting the up and downmovement of the rear driven axle which is supported upon springs 105.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

lfA transmission mechanism comprising a motor, a balance wheel therefor,a trans mission mechanism including a clutch member co-acting with theinterior surface of the balance wheel, said clutch member projectingbeyond the said balance wheel rim, and a reversing mechanism co-actingwith the outer peripheries of said balance wheel rim, and the projectingportion of said clutch member.

2. In a motor vehicle, the combination of an explosive engine providedwith a crank shaft, a connecting shaft, a vehicle driving aXleoperatively connected with one end of the connecting shaft, the oppositeend of the connecting shaft and crank shaft having respectively a gearand a flange or collar, one of said latter members provided with acoacting movable clutch member, and a reversing mechanism including agear meshing with the aforesaid gear, and a friction roller adapted toengage said collar.

3. A transmission mechanism comprising a motor, a balance wheeltherefor, a driven shaft, a movable rotatable clutch member I rection,and a reversing mechanism including two operatively connected oppositelyrotating wheels, one of said wheels actuated by the balance wheel, andthe other of said wheels operatively connected with said clutch memberto rotate it in a direction opposite the direction of rotation of thebalance wheel.

1. In a motor vehicle, the combination of an explosive engine having acrank-shaft provided with a collar or sleeve, :1 connecting shaft, avehicle drive shaft operatively connected with one end of saidconnecting shaft, the opposite end of the connecting shaft having aclutch member adapted to co-act wlth the inner surface of said collar,the adjacent end of the connecting shaft having a gear wheel, and areversing mechanism including a gear adapted to engage the aforesaidgear and a friction roller adapted to engage the outer surface of thecollar and co-acting with said gears to impart a reverse motion to theconnecting shaft.

5. In a motor vehicle, the combination of an explosive engine having acrank shaft, a vehicle drive shaft, a connecting shaft having one endoperatively connected with the vehicle drive shaft, the adjacent ends ofthe crank shaft and connecting shafts having respectively a gear and afriction collar, a clutching mechanism between the collar and theadjacent end of the connecting shaft, and a reversing mechanismincluding a movable frame having a friction roller adapted to be carriedin engagement with the said collar, the friction roller provided with apinion, and a gear between said pinion and the gear carried by theconnecting shaft, whereby the reversing mechanism may be thrown intooperation or entirely out of operation when not in use.

In testimony whereof I afiix my signature in presence of two witnesses.

ALEXANDER IVINTON.
